The fresher the salmon, the better! I love using wild-caught salmon for maximum flavor, but farmed salmon works well too.
I don’t cover the salmon while baking because the glaze needs time to thicken and caramelize. Covering it would prevent that from happening in just 20 minutes.
I’m careful not to overcook the salmon—it should be tender and flaky, not dry. I take it out of the oven when the internal temperature is close to 145°F.
Another way I check for doneness is by gently flaking the salmon with a fork. If it flakes easily, it’s ready to come out of the oven.
